Plants have unisexual male or female flowers that are white or yellow and borne on 40-millimetre-long (1 + 1 ⁄ 2 in) hairy stalks. Each flower grows singly in the leaf axils, and the species' sexual system, with male and female flowers produced on each plant, is monoecious. The male flowers predominate at the beginning of the season; the ...
